Beetle ESP32-C3 IoT Development Board

1. Getting Started

The article provides a step-by-step guide for first-time users of the ESP32 development board, detailing how to configure Arduino IDE, select the appropriate board settings, and execute a simple LED blinking program. It covers essential configurations such as USB CDC settings and partition schemes, ensuring a smooth setup process for beginners.

2. Example Code for Arduino-SmartConfig configuration

Through this code, Espressif's ESP-TOUCH can be used for one-click network configuration.

3. Example Code for Arduino-Bluetooth Receive and Transmit

This example demonstrates the data transmission between ESP32-C3 and the mobile phone. If you need to modify or use the data, you only need to change the data receiving part or the data transmitting part of the code.

4. Example Code for Arduino-Two ESP32C3 Bluetooth Communication

Use this example to demonstrate the data transmission between ESP32-C3 and ESP32-C3. If you need to modify or use the data, you only need to change the data receiving part or the data transmitting part of the code.

5. Example Code for Arduino-WIFI control LED

ESP32C3 has WIFI function, the following example uses ESP32C3 to create a wifi server, use the client to connect to the server, and control the on and off of LED.

6. Example Code for Arduino-ESP-NOW Data Transfer

ESP-NOW is a kind of connectionless WiFi communication protocol which is defined by Espressif. It can be widely used in smart light, remote controlling, sensor, etc.

7. Example Code for Arduino-WIFI to obtain temperature and humidity

This example is based on Example 8.3 to further learn the information transfer of Wifi under the LAN. You can learn how to access the IP address under the LAN to obtain the temperature and humidity sensor status of the SHT30 in another place.

8. Example Code for Arduino-display measured temperature and humidity

Getting the temperature and humidity displayed on the OLED screen is a very intuitive and interesting project. Below you will learn the basic OLED display and use the I2C interface to obtain the temperature and humidity sensor data.

9. Example Code for Arduino-Get the weather with WIFI

This example is used to let you learn how to get weather information and let you experience the information obtained in HTTP which extract data through Json and print it.

10. Example Code for Arduino-Get network time with WIFI

This example demonstrates getting the time from a network time server and using the RTC clock that comes with the ESP32 to keep the time updated.
